Once I asked my teacher, my grandmother, why a certain man in our village never seemed to be happy, even though he had all of life's advantages — he was healthy, he had a fine family and a good job, and he even had a full head of hair. Her reply was simple but profound: "It is not possible for life to make a selfish person happy, whatever temporary satisfactions may come along. But," she added, "life cannot but give you joy if you live for the joy of others."
